Question 2

Percentage of nitrogen and oxygen in atmosphere

Answer 2

N 78% 0 21%

Question 3

Weather

Answer 3

Instant state of the atmosphere, daily values of temperature, precipitation, pressure, windspeed. Short period of time

Question 4

Climate

Answer 4

Average values, average behaviour of continents, oceans, atmosphere. Long period of time

Question 5

Difference between weather and climate

Answer 5

Measure of time. Weather= conditions short period of time. Climate= how the atmosphere behaves in long periods of time

Question 6

Atmosphere functions

Answer 6

Solar radiation filtration
Breathing photosynthesis
Regulation of:
Earths temperature
Biogeochemical cycles
Hydrological cycles

Question 7

Radiative (climate) forcing

Answer 7

Difference of insolation absorbed by earth and energy radiated back to space.
Insolation absorbed- energy back release

Question 8

Radiative forcing is quantified at the

Answer 8

Tropopause

Question 9

Positive forcing means

Answer 9

More incoming energy, so warms the system

Question 10

Negative forcing

Answer 10

More outgoing energy, so cools the system

Question 11

Climate factors

Answer 11

Physical and geographical conditions that are relatively constants in time and space, and related to energy transfer (heat)

Question 12

Examples climates factors

Answer 12

Latitude, altitude and distnce from the sea, ocean drifts, vegetation coverage, water bodies, pressure and wind system

Question 13

Earths atmosphere is moving due…

Answer 13

Differential action of the surface warming

Question 14

Tropics receive more heat than poles due….

Answer 14

Solar rays are more perpendicular, cross sectional area is smaller, and thickness of atmosphere higher at poles

Question 15

Earth atmosphere gets THINNER the HIGHER altitude because……

Answer 15

Higher ground presents less atmosphere material to store heat

Question 16

Explains continentality

Answer 16

Summer= land and seas store heat from the sun
Land reflects more heat than seas
Winter= land and seas release heat stored
Ocean have more heat to release than sand

Question 17

Ocean drifts transports..

Answer 17

Large amount of heat throughout the world

Question 18

Oceans have a fast or slow response time to changes?

Answer 18

Slow

Question 19

Permanent gases in atmosphere

Answer 19

N, o,
